I have a suspicion that you are feeling something different than what you think. I, only one time, have experienced brake fade in my car. I did about 15 high speed autox runs in a row, with no rest between. Each one of these included 2 90-30mph stops. I ended up boiling the fluid in the brembos. The car is a garage queen, and only has about 8,500 miles on it. I had not bled the brakes since I bought it at 4 miles, and it's about two years old. Side note, I was also running race slicks.
So, let's just say the factory brembos aren't bad, and unless you are on an actual race track, you're probably going to be fine. Even then, just don't let your fluid sit for more than a year or so.
Sidenote: to back on what Bill said, ATE is great fluid. The blue is a bit more expensive now since the EPA or whatever decided they should dictate what color fluid is, but the type (typ) 200 is the same, albeit a regular amber/clear color. FWIW, I've used blue in all the performance stuff I've had for the last few years, and have never had an issue. Since I am doing this car now, I ordered the amber from BAS for about $35 shipped for two liters. It's only slightly lower of a boiling point than SRF, and about 25% of the price. YMMV.
